04-generate-runtime-deps.sh: introduce skiprdeps

Yet another variable to permit skipping of runtime dependency checks
for a list of files, specifying their absolute path in the $DESTDIR,
allows us to handle known bad detections due to e.g. binaries or
shared libraries not meant to be run or loaded in the host.

This will be used to fix the android-studio template to skip
a number of files which would create a bogus dependency on libc.so.
